The thing to be careful of when buying a used gun (and even more so on-line sight unseen) is not the reputation but whether a previous owner has messed with it, and that is not always evident even when the gun is in the hand. A sad story that appeared recently involved a revolver bought used, but which then turned out to need a new hammer and trigger. It had been a good deal, but the cost of parts and repair made it no bargain.
